Answer keys to be improved

I find that some puzzle types' answer keys cannot be used in extreme circumstances. For example, if the answer key for a Four Winds puzzle with all clues being 4 is the same as in PGP 2026 R2, or the answer key for an Araf puzzle with all clues being 5 and 7 is the same as in PGP 2022 R7, then the answer key is obvious without solving the puzzle. Therefore, I think the answer key for some puzzle types should be improved to handle extreme situations.
